1. 14 Pin Receptacle: This receptacle allows the power
source to interface with wire feeders, and remote
controls such as a foot pedal. This receptacle provides
auxiliary power, contactor control for energizing the
output of the power source, and remote output control.
The pinout is as follows:
A) 24 VAC auxiliary power high side
B) 24 VAC Contactor circuit, (closure between pin A
and pin B will energize output).
C) Remote control maximum (top side of remote
control)
D) Control circuit common
E) Remote control in (wiper of remote pot., 0 to 10
Volts). CV mode: 0 to 10 Volts gives 10 – 44 Volts
of output. CC mode: 0 to 10 Volts gives 5 – 560
Amps of output.
F) Scaled output current signal: Ifb = 100 Amps/Volt
G) 24/115 VAC neutral
H) Output voltage signal: 10 Volts/Volt
I) 115 VAC auxiliary power high side
J) 115 VAC Contactor circuit, (closure between pin I
and pin J will energize output).
K) Chassis ground
L) N/C
M) N/C
N) N/C
2. 19 Pin Receptacle: This receptacle allows the power
source to interface with wire feeders, and remote
controls such as a foot pedal. This receptacle provides
auxiliary power, contactor control for energizing the
output of the power source, and remote output control.
The pinout is as follows:
A) Contactor circuit (+15 Volts)
B) Contactor circuit in, (closure between pin A and
pin B will energize output).
C) Scaled output voltage signal: Vfb = 10 Arc Volts/
Volt
D) 24 VAC auxiliary power high side
E) 115 VAC auxiliary power high side
F) 24/115 VAC neutral
G) Chassis ground
H) Remote control maximum (top side of remote pot.)
J) Remote control in (wiper of remote pot., 0 to 10
Volts). CV Mode: 0 to 10 Volts gives 0 – 44 Volts
of output. CC Mode: 0 to 10 Volts gives 0 – 560
Amps of output.
K) Remote control minimum (bottom side of remote
pot.)
L) Control circuit common
M) Arc Established = +12 Volts
N) Control circuit common
